Found them on a 60 GMC truck.

I think this post is old, but was wondering if you ever got to the bottom of your question? I have a 1963 GMC and had the same plugs until I recently yanked em. I'd like to know what the original purpose of these holes were.

I wonder if they are for the "cheap" heater? those kind had two knobs, one for vent, and one for the fan.

Interesting...

The next time I am out at kellys wrecking yard, I will try to get a bunch of pics of gmc dashes for you, he has 20 or so, and I seem to remember seeing a cheap heater.

His/Hers ejector seats

cheap heaters is exactly what they are my truck only has one hole 65 gmc pull knob out for heat turn to the right for increased blowing power from vents, here is a pic.

My '61 GMC has them too,and I asked on another forum as well
Nobody seems to know what they're for
They must be for something or they wouldn't be there??
I can't help but think they're heavy truck related (low air warning light or ??)
Also noticed that they're a bit far away for any kind of driver use,ie, heater control

this is the dash on my 66 GMC, same plugs, except that the PO moved the choke cable fro the door side over to the ignition side, weird

Iamthor was referring to the two next to the glovebox

Turns out these are the perfect size for two push buttons I have for a shaved door handle solenoid kit. I'm not too keen on shaved door handles, but that's how the truck came. They did a nice job welding the doors and smoothing things out, but a horrible solenoid set up (it was soo ghetto). Anyhow, short term fix will be an Autoloc set up i purchased from eBay and the interior buttons fit perfect. I'll post pics someday!
